Abstract (en)

A manual leveling control system and method for construction equipment is provided. The manual leveling control system for construction equipment includes a swing angle sensing unit sensing a swing angle of an upper swing frame and transmitting a signal for the sensed swing angle; a tilting manipulation input unit generating and transmitting a tilting manipulation signal corresponding to coordinate values on a coordinate system, having coordinate axes corresponding to left/right direction and front/rear direction of the upper swing frame, in accordance with a position manipulated by a user; and a control unit determining target actuators to be operated among actuators radially positioned around a tilting unit using the coordinate values of the tilting manipulation signal and the swing angle of the upper swing frame, and calculating operation values for determining whether to extend/contract the target actuators and operation ranges of the target actuators, in order to tilt the upper swing frame against a reference surface in accordance with the tilting manipulation signal.
